Actresses are notoriously difficult for JavLuv to manage, due to the nature of the Japanese language, and how there isn't really an exact English name for a given Japanese name. Add to this the issue that actresses sometimes change names throughout their careers (some have many aliases), two possible name orderings, and the problem grows even more tricky. Hibiki Otsuki is my favorite example, as there are no less than three valid ways to spell "Otsuki".
I attempt to alleviate this with fuzzy algorithms that employ a "closest match" in case of minor spelling differences, but I didn't want to introduce too many false positives. It works most of the time, but does sometimes require manual intervention.
If there's a name with no corresponding database entry, JavLuv will create one, or else it ends up having issues. If you delete it, it will just be recreated later. So, merging it is the correct answer, as this will also merge names such that the alternate name is preserved.
In theory, JavLuv should have dealt with name order, so long as the websites scraped from display the name consistently. So I'm not sure why that's occurring.
